T0 aZZ whom, it may concern:

Be it known that I, HENRY C. CREEDON, a

residing at T0- ledo, in the. county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Bedfiqpring Locks, ofwhich I the following is a spec cation.

The present invention relates toimprovements in bed-springs, and moreparticularly to a novel locking device whereby the various individualspring members within the frame are held in a fixed position withrelation to each other and are'prevented from having any lateraldisplacement.

A further feature of the invention resides in the fact that the variouselements constituting the lock cooperate with each other to form aseries of braces extending throughout the frame.

The object of the invention is to provide a lock of this nature which isextremely simple and inexpensive'and which can be readily appliedwithout the use of a power stretching-table or other costly apparatus.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction of the meansfor effecting the result reference is to be had to the followingdescription and accompanying drawings, in which- Figure 1 is a top planView of a portion of a bed-spring constructed in accordance with theinvention. Fig. 2 is a sectional view through the same, and Fig. 3 is aperspective view of the lock between the individual springs.

Corresponding and like parts are referred to in thefollowing'description and indicated in all the views of thedrawings bythe same reference characters.

The invention is shown as applied to a bedspring, in which the numeral 1designates the outer frame, and 2 the individual spring members,whichare arranged within the outer frame in a series of parallel rowsand which are held relatively in fixed position by means of the lockingdevice. Extending along one side of each of the rows of spring members 2is a cross wire or strand 3, which is crimped at a point adjacent eachof the spring members to form the laterally-extending loops 4, theextremities of which bear against the corresponding spring members 2 inthe adjacent row. These loops 4 preferably comprise the two arms 5,.which in the present instance converge, and at their junction with thecross-wire 3. are provided with the offset portions 6 ,which throw theloops. 4 into a plane spaced. fromthe plane of the cross-wires 3. Oneside of each of the individual spring members 2 is brought intoengagement with these offset portions 6 and the spring member therebyeffectively held against any latsprings 2 in position and of preventingany longitudinal slipping .of the tie-wires 7. In the exact arrangementof the various parts it will be observed that the loop 4 has its twomembers converging throughout their length and that said loop by reasonof the offset portion 6 lies straight across the upper side of twoadjacent spring members. The tiewire 7 as it extends from one springmember to the other passes across one spring member contiguous to andbetween the offset portion 6 and on the opposite side of the springmember from the loop 4, and thence said tie-wire extends to the nextspring member and across the same on the side opposite the loop, andthence is offset vertically in substantial y ogee formation to projectupwardly through the small end of the loop and cross the upper side ofthe loop, being crimped partially around both the spring member and thecross-connecting portion of the loop, which is joined to the two arms 5,as best seen in Fig. 2. By this arrangement not only do the offsets 8increase the effectiveness of the tiewires 7 as braces for the frame,since a tension member is much stronger, (when braced at a plurality ofintermediate points than when simply connected at its extremities,) butat the same time it is believed this arrangement promotes economy in themanufacture of the bed-spring bottoms, because it is much easier to benda single strand, such as the tie-wires 7 than to bend the two arms 5 atthe small end of theloop 4 to secure any crimping and loop effect atthis point.

With this constructionit will be apparent that the various springmembers 2 within the frame are each engaged upon opposite sides by theoffset portion 6 in the cross-wires 3 and the offset portions 8 in thetie-wires 7, respectively, and are thereby effectively held against anyswaying movement or lateral displacement.

An important feature in this invention also resides in the fact that anyweight brought to bear against the springs simply tends to tighten thelock and hold the spring members more securely against displacement.Owing to the fact that the locking-wires 7 are formed at intervals withthe offset portions 8, the same are held against any longitudinalslipping through the cross-wires 3 a and are consequently braced at aseries of intermediate points. As a result of this feature a series ofbrace members are formed which not only reinforce the outer frame 1, butalso connect the various parallel rows of spring members 2. Theformation of the locking device with the offset portions 8 also has thefurther advantage of enabling the tie to be applied to the frame withoutthe necessity of employing a power stretching-table or other expensivemachinery.

Having thus described the invention, what is claimed as new is In abed-spring bottom, the combination of a frame, a plurality of springmembers in the'frame, cross-wires extend ng across the frame andprovided at intermediate points with loops, the arms of which convergethroughout their length, said loops being 011'- set from the plane ofthe cross-wire and extending straight across one side of two adjacentspringmembers, and tie-wires extending across the frame at angles to thecrosswires, said tie-wires extending across two adjacent spring membersupon opposite sides from the sides where the loops are located, saidtie-wires being crimped around the spring members at the small end ofthe loops and extending upwardy through the small end of the loop andthence across and crimped partially around the cross portion connectingthe two converging arms of the loop, as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

HENRY C. CREEDON.
